hi ive just bought a mk4 2ltr gti and want to make it go quick. being new to all this and needing a new exhuast so wanting to kick it of there,where do i start.
How old is the Golf? Get the new exhaust fitted first then contact some tuners about getting the car remapped would be a good start. There are some specialist Golf companies who have a good reputation, I shall leave the naming of these to the members on here who have actually used them.
